Focal tracheal stenosis due to intramural hematoma following endobronchial ultrasound-guided transbronchial needle aspiration.

Tracheal obstruction can present insidiously or be acute and life threatening. This condition can occur acutely, as in cases of infection or foreign body aspiration, whereas posttraumatic tracheal stenosis or obstruction due to intraluminal tumor growth typically evolves more gradually. Tracheal stenosis secondary to intramural hematoma is exceedingly rare. We report a case of intramural tracheal hematoma causing obstruction following endobronchial ultrasound-guided transbronchial needle aspiration in a 69-year-old woman.
